ABSTRACT
Response characteristics of a microhole potentiostatic oxygen sensor and a Beckman membrane oxygen sensor were measured in a laboratory over temperatures ranging from 1° to 21°C. The response term of the microhole sensor changed 1.7-fold over this temperature range, and of the membrane sensor changed 1.6-fold. For the microhole sensor, the effect of temperature on can be modeled as ln+6.5 + 1618T¹. For the membrane sensor the temperature effect on can be modeled as ln = 5.8 + 2116T¹, where T is temperature in kelvins.
